Previous version has A64-Relic board, which has some xclk issue on sensor side wrt 1080p. I have tried 300MHz on the same hardware, it's failing to capture on 30fps and so I tried 600MHz(which is default) on the same configuration but it encounter memory corruption. So, for checking whether there is an issue with hardware on A64-Relic I moved with BPI-M64 dev board. which is working 1080p with 300MHz, ie reason I have not included A64-Relic on this version and included BPI-M64. We processed A64-Relic to hardware team to figure out the clock and once ie fixed I'm planning to send DTS patch for that. This is overall summary, hope you understand. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
